This explains how to check DC power supply, I-Mark
sensor level, Gap/center hole sensor level, ribbon sensor
level, side hole sensor level, R-corner hole sensor level
and jump hole sensor level. Ensure printer power is OFF.
Then remove the VR cover on the back of the printer and
perform the following steps.
Additional equipment required
TP Test Module
Digital Multimeter
STEPS
1 Attach the connector from the TP Test Module to the
test port on the MAIN PCB. Note correct positioning
of connector. Nibs on the connector are placed down
on the PCB in the forward position.
2 Attach the ground probe of the Digital Multimeter to
the TP Test Module ground pin (GND PIN).
3 Attach positive probe of the Multimeter to the +SIG
PIN on the TP Test Module terminal.
4 Turn printer power on and rotate the dial to a dial
POS on the TP Test Module. Record the values from
the Multimeter.
5 Confirm voltages are correct. If not, then replace
parts or adjustment sensor level. Refer to Check and
Adjustment chart.
6 After p erforming test, put the VR cover b ack to
the printer.

Ribbon Clutch
Adjustment
Excessive ribbon unwind and rewind tension will result in
variable motion and could be the cause of print quality
problems. Ensure the ribbon rewind and unwind tensions
are within specifications or adjustment of either clutch is
necessary.
STEPS
1 Switch the printer OFF and disconnect the power
cable.
2 Open the top and front access door. Remove the
ribbon and label stock if installed.
3 Attach string to an empty ribbon core and place
on the Ribbon Spindle. Wind the string tightly around
the ribbon core in single layer and in clockwise direction.
Attach the end of the string to the tension guage.
4 Gradually lift the tension gauge, pull the string and
unwind it from the core. Once the spindle starts to
move, the gauge should indicate 500 to 700 grams of
tension for ribbon rewind, and 400 and 500 grams of
tension for ribbon unwind. Refer to picture in next page.
5 To adjust the clutch, loosen the locking screw and
move the adjust nut CW for more tension and CCW
for less tension. Tighten the locking screw and repeat
steps 3 and 4 until the correct tension is achieved.
